Question

a scuba diver descends 48 feet in 4 min. What is the divers average change in position per min. relative to where she started?

Answer 1

With this you need to find the unit rate so divide 48 by 4 to get 12, so the scuba diver descended 12 ft. per min.

Answer 2

-12 ft/min

Explanation:

We are given that scuba diver descends 48 feet in 4 min.

We have to find the average change of divers in position per min.

Total distance covered by diver=-48 feet

Time taken by diver=4 min

Average change=
`-(48)/(4)` ft/min

`average=-12 ft/min`

The diver descend 12 feet in one minute.

Where negative sign shows that diver going to downward.

Answer:-12 ft/min
